Fees

Ratio uses a transparent, volume-tiered fee model. There are no hidden markups, no post-trade adjustments, and no opaque spread loading that disguises the true cost of a transaction. Every fee component is visible in the quote response before you execute.

​
Fee components

Every swap involves two cost components: Platform fee — A per-transaction fee with two parts:
  • A variable component: a percentage of the transaction amount.
  • A fixed component: a small flat amount denominated in the destination currency.
The platform fee covers protocol operating costs and contributes to LP rewards. Spread — The difference between the bid and ask prices in the quote. Ratio’s spread is constructed dynamically from four risk-based components: base, volatility, liquidity, and inventory. The spread compensates LPs for providing instant execution and covers the cost of maintaining pool health. See Oracle Pricing for a full breakdown of each component. Together, the platform fee and spread represent the total cost of your transaction. Both are visible in every quote response — you see the full cost before you decide to execute.

​
Volume tiers

Ratio’s fee schedule is volume-tiered: larger transactions receive tighter rates. This mirrors institutional FX pricing, where volume earns better execution. Each corridor has its own tier schedule. As transaction size increases, both the variable fee rate and the base spread component decrease. The largest transactions receive the tightest pricing.
TierApproximate rangeWhat you get
MICROUnder ~$1,000Standard rates
SMALL~$1,000–$10,000Improved rates vs. MICRO
MEDIUM~$10,000–$50,000Meaningfully tighter spreads
LARGE~$50,000–$200,000Near-institutional pricing
INSTITUTIONAL$200,000+Tightest available rates
Exact tier boundaries and rates vary by corridor. Your account manager will provide the specific fee schedule for each corridor you access during onboarding.

​
Fee visibility in quote responses

Every firm quote response includes a fee_breakdown object that details every cost component: 
{
  "fee_breakdown": {
    "platform_fee": {
      "variable_fee_bps": 8,
      "fixed_fee": "0.50",
      "fixed_fee_currency": "IDRX"
    },
    "spread": {
      "base_bps": 3,
      "volatility_bps": 1,
      "liquidity_bps": 2,
      "inventory_bps": 0,
      "total_spread_bps": 6
    },
    "total_cost_bps": 14
  }
}
You can display this breakdown to your end users or use it for internal reconciliation and reporting. The rate shown in the firm quote is the rate you receive at execution — no post-trade adjustments.
Use total_cost_bps to compare execution cost across corridors and transaction sizes. It gives you a single number representing the all-in cost of the transaction in basis points.

​
Partner-specific pricing

In addition to the standard tier schedule, Ratio supports per-partner fee overrides. Strategic partners — such as anchor liquidity providers or high-volume remittance operators — can receive customised pricing that reflects their contribution to the ecosystem. Partner overrides can adjust the variable fee, fixed fee, or base spread for specific corridors and size tiers. When a partner override is active, the fee_breakdown object in the quote response includes "is_partner_override": true so you can identify when customised pricing is in effect. Partner-specific pricing is configured during the onboarding process. Contact your account manager to discuss whether your volume qualifies.

​
Revenue distribution

Swap revenue is distributed to three recipients:
  • Protocol treasury — Funds ongoing development, infrastructure, and operations.
  • Pool LPs — Rewards liquidity providers who funded the specific pools used in your swap.
  • Global fee pool — Distributed to all LPs across the platform, aligning incentives for broad, deep liquidity.
This distribution model aligns the interests of the protocol, liquidity providers, and partners — everyone benefits when the platform is well-used.
